Abstract

This disclosure is related to the field of semiconductor technology, more specifically, to a flexible touch sensor and display device including the flexible touch sensor. The flexible touch sensor is formed through the construction of chain structure formed by flexible conductors and rigid conductors, that is, based on the principle of chains, connecting the rigid conductors and flexible conductors in an interval way, to form a chain structure, and making the manufactured sensor and the display device reach the purpose of being flexible, and the problem caused by the immature of the development of flexible materials that the flexible sensor can't be mass-produced can be effectively solved.
